Breakfree has a product called "Collector". Go to their website and read up on it. They claim you can coat a weapon with it and leave it in storage for 5 years and it will be protected and ready to grab and shoot with no evaporation or gumming up and no need to remove the product. I have been using it on my safe queens for about 5 years now and it does work very well as a preservative. I carry blued revolvers IWB in hot summer weather and sweat on them and I have never seen any rust. Breakfree CLP is very hard to beat. I have never seen CLP dry out or turn to gunk in all of the years I have used it. The entire Breakfree line of products are extremely good.
